I have a raw disk backup of a 4TB external drive /dev/sda split into 1GiB chunks, within is a single used partition /dev/sda1 and some other junk. The chunks are being stored on multiple physical drives as they are all smaller than 4TB. What's the easiest way to mount or at least extract files in a recovery scenario?
The external drive or filesystem is having issues (mounts but explorer locks up when filesystem explored), but /dev/sda can be dd'd so I've made a backup before attempting a fix with fsck or whatever.
fdisk ouput, which fails because there's more than2^32 512 byte sectors:
